i386: Cleanup V2QI arithmetic instructions
2022-01-13 Uroš Bizjak <ubizjak@gmail.com>
gcc/ChangeLog:
* config/i386/mmx.md (negv2qi): Disparage GPR alternative a bit.
Disable for TARGET_PARTIAL_REG_STALL unless optimizing for size.
(negv2qi splitters): Use lowpart_subreg instead of
gen_lowpart to create subreg.
(<plusminus:insn>v2qi3): Disparage GPR alternative a bit.
Disable for TARGET_PARTIAL_REG_STALL unless optimizing for size.
(<plusminus:insn>v2qi3 splitters): Use lowpart_subreg instead of
gen_lowpart to create subreg.
* config/i386/i386.md (*subqi_ext<mode>_2): Move.
